He did not complete Tawaf-ul-Ifadah due to his illness

Q: I went to perform Hajj one year and on the 10th day of Dhul-Hajjah I threw Jamarat-ul-`Aqabah (the closest pebble-throwing area to Makkah). Then, I went to Al-Haram to perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) but there was a great crowd. So, I performed the Tawaf on the roof of Al-Haram but at the end of the fourth round of Tawaf I had internal abrasions and I could not complete the seven rounds of Tawaf. Some (Part No. 10; Page No. 228) pilgrims suggested that I postpone the Tawaf to Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) and it will be sufficient. I returned to Mina and on the 12th day I threw the Jamarat (stone pillars marking the pebble-throwing area, Jamarat-ul-`Aqabah being the closest to Makkah) at 12 P.M. Owing to the great crowd and after that I went to Al-Haram to perform Tawaf-ul-Wada`. I did not perform seven rounds but I performed only three rounds completing the former four rounds. What is your opinion on this? Is my Hajj valid or not? Answer me.

A: If the case is as mentioned, the Tawaf is invalid. You have to return to Makkah and perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Sa`y (going between Safa and Marwah during Hajj and `Umrah) if you were Mutamatti` (pilgrim performing `Umrah during the months of Hajj, followed by Hajj in the same year with a break in between). Also, you should perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) if you do not leave immediately after Tawaf-ul-Ifadah. However, if you were offering Qiran Hajj (combining Hajj and `Umrah without a break in between) or Ifrad Hajj (performing Hajj only) and made the Sa`y after Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah), you would not have to offer the Sa`y. Otherwise, you should perform it after Tawaf-ul-Ifadah and make Tawaf-ul-Wada` if you stayed after Tawaf-ul-Ifadah and the Sa`y. If you had sexual intercourse during the time between Hajj and making Tawaf and Sa`y, while you still had to offer it; you are required to slaughter a sheep meeting the same conditions for Ud-hiyah (sacrificial animal offered by non-pilgrims) and distribute it in Makkah among the poor people of Al-Haram. This is because you did not perform the second Tahallul (removal of the ritual state for Hajj and `Umrah).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
